I am trying to run snakemake on an offline system, have managed to download and install all obvious dependencies and install snakemake. However, a rule with benchmark file specified was crashing without visibly raising a meaningful error while the same rule without benchmark part was working just fine. The problem disappeared after the psutil was installed. It looks like code on lines 16-20 of benchmark.py may not be doing what's expected.
Snakemake versions 5.5.3, 5.6.0
